it doesnt matter what you plug it into, or where it is on the chain. it will see it all the same.
after you get this all setup with your lights. and want your RSS feature to work in a siggy like mine (have to make it smalller for it to work on this site), head over to reefchat.org and make a siggy. its a bit confising at first, but you'll get the hang of it.
anyone know how to program the DA ATO?
also for the hystersis, you might want to make the value a little higher for the heaters. i made mine .5 degrees. if i kept it lower my heater would click off and on too much and drove me nuts. my Ca reactor soleniod sounds like someone is doing that mexican dance with the spoons...... anyone know of a quiet solenoid for the CO2 regulator? i got the milwalkee one and it clicks too loud.
